Http Web请求和响应发送多帖后（10）得到我错误的响应

Question

嗨，我正在使用此代码来使我的程序检查器<并且此代码工作得很好<，但是在检查器中我是10个用户名之后，响应使我感到失望，而在我等待了2分钟后，休息检查器使我获得了良好的响应 我需要帮助什么问题 如果在回复失败后使用vpn，请让我重新检查并获得良好的回复 我认为服务器让我阻塞了我的IP几分钟，然后再次工作 我需要检查不止1000个用户名，或者每天获取我

This is a first request and response It is a good not have any problem

After check maybe 10 username get me this response I don't know what is the problem
